Peak power output (PPO), also known as "peak work rate" is a common measure of exercise intensity.For example, researchers may ask subjects to complete an incremental exercise test where VO 2 max is measured while the person cycles at increasingly difficult power generation levels as measured by a cycle ergometer.
These findings suggest that warm-up is an unimportant factor in peak power levels, but if mean power is the variable of interest it is important to standardize the warm-up. Since the Wingate test stresses the anaerobic metabolic systems glucose consumption pre-testing can be another influential factor.
The Margaria–Kalamen test has been a standard test for determining peak power for some time, and at one time was thought to be a measure of the power of the pure alactic anaerobic system. However, it is now thought that even on such a short test, there is still a significant contribution from the lactic anaerobic system.

Some studies measure exercise intensity by having subjects perform exercise trials to determine peak power output, [4] which may be measured in watts, heart rate, or average cadence (cycling). This approach attempts to gauge overall workload. An informal method to determine optimal exercise intensity is the talk test.
Peak Power. Training at loads that elicit peak power is a common and desirable objective in many sports. [ 33 ] [ 12 ] [ 15 ] [ 14 ] Many velocity tracking technologies calculate peak and mean power levels providing values in absolute terms and relative to an athlete's bodyweight.
A similar measure is V̇O 2 peak (peak oxygen consumption), which is the measurable value from a session of physical exercise, be it incremental or otherwise. It could match or underestimate the actual V̇O 2 max. Confusion between the values in older and popular fitness literature is common. [3]
The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...
